Water is analyzed all over the world because water contains contaminants that can make sick or even kill humans. You can then list the types of parasites, etc., that live in the water to give examples. Most water systems today, even in the most advanced cities of the world, cannot keep out germs and pollutants.

I am afraid I don't really understand this question. You don't specify a particular type of water analysis and I can't figure out where a "lecture" comes in.
Water is analyzed for many different reasons. Drinking water plants, analyze water to make sure it is drinkable and will stay drinkable. Their tests often include assays for metals such as lead, cadmium, and arsenic. They also usually test for fecal coliform bacteria and residual chlorine.
Waste-water analysis is required in many places for companies or municipalities that dump water into a stream or river. The analysis required depends on the type of operation, but often includes a "grease and oils" test, a BOD (biological oxygen demand), and assays of specific chemicals.
We analyze water that will be used for feeding a boiler to make sure it is properly pretreated and we analyze cooling water to determine if salts are building up too high (or our cycles are correct for our treatment).
In fact, there are countless kinds of water analysis and therefore many many procedures. Since water enters into so many aspects of our lives, their are water analyses for almost everything.

You first have to decide what is "normal." Are talking about drinking water, rainwater, well water.....
We generally analyze water to see if it meets a specific requirement. If you are talking about drinking water, we look for total organics, sometimes hardness, and certain specific compounds that have been identified as "toxins."
If you are talking water that is used in industrial applications, you may want to analyze for organic compounds and hardness. Things like calcium and magnesium which can cause scaling in certain processes.
Water has many applications other than drinking...so people analyze it to make sure that it does not have contaminants that will cause problems in the intended application.

To be brief water is analyzed to make it drinkable by removing toxic chemicals in it.In industry al ot of uses to analyse it,To get fertilizers,to make textile dyed properly.These are very very few examples or reasons to analyse water.

The book you need to review (and it is not online for free) is commonly called Standard Methods. It is updated on a regular basis.
